ARENA hardware, or the part you stand on, containing a battery powered motor and computer, which connects to your phone via bluetooth. The Platform houses the cable that connects to each attachment.

Ankle Strap

Padded cuff attachments used for unilateral exercises that often target the psoas, gluteus medius, adductors and abductors.


Hardware that connects to the ARENA cable using a carabiner. Attachments allow you to vary your grip and exercise modality when using ARENA


Amount of energy that you use during an ARENA workout


An ARENA mode that allows you to complete movements at your own discretion. This mode does not require a membership.


The amount of power generated during an ARENA workout, which is the average energy you expend. Too little rest (skipping the rest period) causes intensity to rise but also makes it hard to recover. Too much rest causes your intensity score to fall, making it hard to progress. Intensity is measured in watts.

The Lift

Daily ARENA standalone workout

Motorized Resistance

The battery powered technology that generates tension on the cable which adds and removes weight.


A series of detailed workouts and rest periods designed to last several weeks

Time Left

The amount of time left in each workout assuming no extra rest is taken and it takes a member 3 seconds to complete a single rep.
